The invention discloses an active control type variable-rigidity anti-side-rolling torsion bar device and a variable-rigidity method thereof. The device comprises a torsion bar, a supporting base assembly connected with a bogie and a connecting rod assembly hinged to a vehicle body, wherein the torsion bar comprises a torsion bar shaft and a rotating arm arranged at the end of the torsion bar shaft, the supporting base assembly is arranged on the torsion bar shaft in a sleeving mode, the connecting rod assembly is hinged to the free end of the rotating arm, the anti-side-rolling torsion bar device is characterized in that the effective arm length of the device is R, and the supporting base assembly is connected with a hydraulic system and can drive the torsion bar and the connecting rod assembly to move synchronously along with driving of the hydraulic system, so that the effective arm length R of the anti-side-rolling torsion bar device is changed. According to the device, active control over the side rolling rigidity is achieved, the requirement for the excellent riding comfort of passengers in the high-speed running process of a vehicle can be met, the overturning coefficient and the derailment coefficient of the vehicle passing through a parking lot line and a turnout at a low speed are reduced, and then the safety and reliability of the vehicle are improved.

    主动控制型可变刚度的抗侧滚扭杆装置及其变刚度方法,包括扭杆、与转向架连接的支撑座组件和与车体铰接的连杆组件、扭杆包括扭杆轴和设置在扭杆轴端部的转臂,支撑座组件套装在扭杆轴上,连杆组件与转臂的自由端铰接,其特征在于所述抗侧滚扭杆装置的有效臂长为R,支撑座组件与液压系统连接,可随液压系统的驱动带动扭杆和连杆组件同步运动,使所述抗侧滚扭杆装置的有效臂长R改变。本发明实现侧滚刚度的主动控制,既能满足车辆高速运行过程中旅客乘坐优良的舒适度,也降低车辆低速通过车场线、道岔的倾覆系数、脱轨系数,进而提高车辆的安全可靠性。
